Nothing is wrong with them. They have huge amounts of traffic, and that's why transactions are taking longer than normal time. Last night I tried to deposit around 190$ worth of BTC into their wallet. It took them more than 4 hours to reach the wallet. I thought that they might not be legit, but after receiving my Bitcoin in their wallet, I found them quite good. Their network is too busy because of so many transactions at the site.You should wait for few more hours so that you can receive your BTC's into your wallet. I found Coinmarkets exchange much faster than Bitfinex, but unfortunately they don't have IOTA in their exchange. And, that's why I used Bitfinex. Otherwise Coinmarkets worked best for me.

Everyone is trying to withdraw from bitfinex at the same time basically because of their 'relationship' with tether and since they aren't allowing an independent auditor to check their finances. Bitfinex is probably going to collapse at some point. Check out @bitfinexed on twitter to find out more.

OP finally did you withdraw it? I guess yes because of your comment "just worked within a few...."Do you read scam accusation threads here? It lt's full of threads named: Bittrex is scam or now they call it new name - shittrex. I think it will be better for you to take those litecoins in your pocket because they blocked some verified people too when they wanted to withdraw good amount of bitcoin + no response from them.
